' CAR-AXLE BOX.

`SCIFCA'JIOI formingpart ofA Letters Patent No. 282,149, dated July 31', 1883.

Application filed May 9, 1883. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM S. G. BAKER, of Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in `Car-Axle Boxes,

object ofthe invention is, iirst, to adapt in an eflicient manner the car-axle boxes of the general character shown in those patents to the trucks of steam-cars as nowin general use, and, second, to improve the general construction.

In the accompanying drawings, Figure, 1 is an end view, partly in section; Fig. 2, avertical section on the line 2 2 of Fig. 1; Fig. 3, a horizontal section on the line 3 3 of Fig. 1; Fig. 4, 'a detail view of the supporting block or step; and Fig.` 5 is a longitudinal Vsection with some `of the parts removed.

The general construction of the axle-box A, the saddle or bearing B, the suspension-link E, thewheel-hub F, and the spring-actuated washer Gr, interposed between the wheel-hubl and the car-axle box, is substantially like that disclosed in the patents above mentioned,'and

needs no description. w

Ihe depending` pedestal H, between the legs or jaws of which the naxle-box Aplays, is rigidly bolted to the framing of the car, and is stayed by suitable braces. rlhe link E, suspended from the top of the axle-box, sustains thesupporting frame or step I, which is provided with a suitable seat for the link on its under face, and is slotted or notched at each end for the reception ofthe `upright sides of the link. This step or seat is illustrated in detail in Figs. 2 audit, from which it will be perceived that guard ridges or projections i are formed on its under face along the sides of `the link-seat, so as to prevent the .link being displaced. Upright lugs i are formed on the upper side ofthe step I, near each corner at the sides of the slots in `the ends of the step, and are preferably curved as shown.` 'Ihe springframe fits down over these lugs, as illustrated in` Figs. 1 and 3, so that lateral displacement ofthe step or spring-frame relatively to each other is prevented. The inner walls of the legs of the pedestals are formed with vertical Arecesses h, preferably rectangular in cross-section, for the reception of the legs of an inverted U -shaped spring-frame, K, which straddles the axle-box and suspending-link, and rests upon the ends of the supporting-step I, which also tsin the vertical recesses h. It will be perceived that as the supporting-step fits in --the recesses in the pedestal-jaws and the link is held in place on top of the axle-box, the axlebox is held against any horizontal turning motion. The spring-frame K is formed on its upper face with a seat or socket, k, for the reception ofthe end of the spring equalizing and sustaining beam L, the lugs of the pedestalbeing slotted at h to accommodate the beam. The opposite end of the beam L is supported in the same way upon another axle-box, and the car-body is mounted upon springs S in the usual way. A brace-rod, Z, extends from `the pedestal of one axle-box to the other. Under this construction the pivot of the suspensionlinkE is its bearing on the under face of the step I, and the car-axle box can move laterally, so as to give ample play to prevent jerks or jars in passing curves, the vertical movement of the block I and the spring-frame K within the pedestal accommodating this action.

Under the organization described and shown it is obvious that the weight of the car-body may be applied on a spring interposed between the body and the upper face ofthe springframe K within the legs of the pedestal. p

In the construction herein described and shown, aswell as in my prior patent, No.

I claim as my inventionl. The combination, substantially as set forth, of the pedestal, the axle-box, the straddling Ushaped spring-frame placed between the Vlegs of the pedestal, the suspension-link, upon which the spring-frame rests, the supporting step or seat sustained by said link, and means for applying the weight of the carbody at the top of the spring-frame.

2. The combination, substantially as set forth, of the pedestal, the jaws of which are provided with vertical recesses on their inner faces, a straddling U-shaped spring-frame,

which fits and moves vertical in said recesses, the axle-box, the link suspended therefrom, the supporting-step, which is sustained bythe flink and receives-the weight or thrust of the spring-frame, and means for applying the weight of the car-body on the spring-frame.

3. The combination, substantially as set4 forth, of the pedestal having vertical recesses on the inner facesof its depending jaws, a straddling U-shaped spring-frame, which fits and 'moves vertically in said recessl the axleboX, the link suspended therefrom, and the supporting-step, which moves vertically in the recess in thepedestal-jaws, and is supported by the suspending-link to sustain the weight of the spr-in g-frame.

4.. The combination, substantially as set forth, ofthe pedestal,"the axle-box, the straddling -U -shaped spring-frame', which fits in the vertical recesses in the pedestal-jaws, the suspending-link, and the supporting-step having a link-seat on its under face and slotted ends for the reception of the link.

5. The combination, substantially as set forth, of the pedestal, the axle-box, the springframe, the suspending-link, and the supporting-step so organized as to hold the axle-box against horizontal turning motion.

6. The combination, substantially as set forth, ofthe pedestal, the axle-box, the aXle so mounted therein as to be held firmly against endwise motion, the suspendinglink, the spring-'frame supported bythe link, and-means for holding rthe axle-box. against horizontal turning motion.

In testimony whereof l have hereunto subscribed my name this 2d day of May, A. l). 1883. l
